and then selling them at auction with 100,000 ... However, their real mileage was sometimes as much as four times the odometer readout

These numbers matter more here. The Cummins/Allison engine/drive-train in these vehicles are otherwise good for 1 million miles before rebuild on average until they are used as delivery trucks. The constant stopping and starting used as delivery trucks cuts that number down to around 480k miles. So they are selling vehicles that will require engine and transmission rebuilds in less than 80k miles. That's very shady. The engine rebuilds are usually around $10k same as a refurbished engine and the transmission rebuild is around $3k. That does not count the cost to install them.

I did have a weird thought, in a organisation as big as FedEx, would they have a pool of spare engines to minimise downtime? You could get unlucky and get a can with an engine that's been through a few chassis and end up with an ECU that knows the engine has done 400k miles whilst the chassis has only done 180k?

Although that's probably a mad theory, if there is hijinks it probably is the good old fashioned kind, probably from this 3rd party middleman rather than FedEx themselves though.
